I just had a look at the very latest git code of powertop:
git://git.moblin.org/powertop
File system tracepoints are used, but the affected power events seem *not* to
be used yet.
Looks like the right time to get this cleaned up.
If you know of any other code making use of these, please point me to the
code, I'd like to analyze whether this would be as easy to adjust as the
perf timechart code was.
Thanks,
Thomas
